摘要：

随着锂离子电池的高速发展，石墨负极电化学性能的提高至关重要。对天然石墨的包覆改性可有效改善石墨负极电化学性能。煤系软沥青来源广泛、价格低廉，是制备包覆沥青的优质原料。介绍了一种以煤系软沥青为原料制备包覆沥青的方法并对试验过程中的影响因素进行讨论研究，制备出的包覆沥青可有效改善石墨负极的电化学性能，提供了一种制备包覆沥青的新思路。

Abstract:

With rapid development of lithium-ion batteries,improving electrochemical performance of graphite anode is of great importance.Modification on the coating of natural graphite can effectively improve the electrochemical properties of graphite anode.Coal-based soft asphalt has a wide range of sources and low price,which is a high-quality raw material for the preparation of coated pitch.In this paper,a method of preparing coated pitch from coal series soft asphalt is introduced and influencing factors in the test are discussed.The coated pitch can effectively improve the electrochemical performance of graphite anode,and a new way of preparing coated pitch is proposed.

Key words: Coal tar pitch, Graphite anode, Coated pitch, Oxidative crosslinking
